The Emmy and Golden Globe-winning actor's role is still kept under wraps, but it's said that he will appear in an episode which marks series regular Mariska Hargitay's directorial debut. The said episode is expected to air in March.

"I'm just going to try and support her," Ice-T said of Hargitay's upcoming directing gig. "And then she's going to actually have Alec Baldwin in a shot, in a scene in the show, and try to direct herself. She's not going to not be in the show."

This will be Baldwin's first starring TV role since "30 Rock" ended its run a year ago. He hosted talk show "Up Late with Alec Baldwin" on MSNBC which debuted on October 11, 2013, but it only lasted for five episodes. The show was canceled following a gay slur controversy involving a paparazzo in New York City.
